Abstract

In order to discuss several representative methods of the gravity anomaly separation and compare their separation effect, the article firstly introduces the principles of those methods, then uses them to test the same set of theoretical model and adopts the preferential regularized filtering methods to separate the Bouguer gravity anomaly in Jiuquan to Wuwei region. Through the analysis of its gravity anomaly characteristics, the regional tectonic background of the work region is preliminarily recognized and following conclusions are summarized: The Bouguer gravity anomaly in the working region is negative; the fault of Longshou Mountains’ southern margin is the most striking gravity gradient zone in the working region and its southwest side is the extension of the Qilian Mountains’ northern margin whose abnormal value changes sharply; the fault structures in the southwest of the work region tend to strike in a nearly east-west or northwest direction, with the southern edge of the Longshoushan fault being the representative; the central and northeastern fault structures are mostly northeast oriented, represented by the Bayanhot Fault and the Yabulai Mountain Front Fault.
